2072-1253=819

Đáp số:819

2072 - 1253 = 819

∛27 - ∛-8 - ∛125 = ∛33 - ∛(-2)3 - ∛53

= 3 - (-2) - 5 = 3 + 2 - 5 = 0

\(\left(125^3.7^5-175^5:5\right):2016^{2017}\)

= \(\left[\left(5^3\right)^3.7^5-\left(5^2.7\right)^5:5\right]:2016^{2017}\)

= \(\left[5^{3.3}.7^5-5^{2.5}.7^5:5\right]:2016^{2017}\)

\(\dfrac{125^3\cdot7^5-175^5:5}{2016^{2017}}\)

\(=\dfrac{5^9\cdot7^5-5^{10}\cdot7^5:5}{2016^{2017}}\)

\(=\dfrac{5^9\cdot7^5-5^9\cdot7^5}{2016^{2017}}\)

Ta có: 
(175⁵ : 5 - 125³ . 7⁵) : 2016²⁰¹⁷
= [(5² .7)⁵ : 5 - (5³)³ . 7⁵] : 2016²⁰¹⁷
= (5¹⁰ .7⁵ : 5 - 5⁹ . 7⁵) : 20162017
= [5⁹ . 7⁵ . (5 : 5 - 1)] : 2016²⁰¹⁷
= (5⁹ . 7⁵ . 0) : 2016²⁰¹⁷
= 0
